An integrated palynofacies, geochemical and petrophysical analysis for characterizing mixed organic-rich carbonate and shale rocks of Dhulian oilfield Potwar Basin, Pakistan: Insights for multiple source and reservoir rocks evaluation

Integrated Analysis of Microfacies, Depositional Environment, and Reservoir Potential of the Sakesar Formation in the Potwar Basin, Pakistan

“…The basin's tectonics are complex and include features such as salt domes, mostly salt-cored anticlines, duplexes, steep faults, reverse and thrust faults systems. Various scholars have carried out detailed research on the basin's evolution, including Fazeelat et al (2010) and Shah et al (2022). The basin encompasses two-thirds of eastern Pakistan, and its major characteristics include the fore-deep comprising depressions, inner and outer folded zones, and Platform (Memon and Siddiqui, 2005;Shah, 2021).…”

“…The basin covers a vast area, comprising two-thirds of eastern Pakistan. Several studies have been conducted on the origin of hydrocarbons, including research by Fazeelat et al (2010) and Shah et al (2022). This study is an attempt to interpret and evaluate the Eocene Sakesar Limestone based on detailed petrographic, petrophysical analysis, and eld studyThe study area is located in the Amir Pur Oil eld and Pail Village section of the Potwar Basin in Pakistan, at the coordinates 32° 35' 57"N, 72° 27 ' 22"E. This region is part of the active foreland folds and thrust belt in Northern Pakistan, near the southern limit of the Himalayan Fold and Thrust system, known as the Salt Range.…”
